 Grades, work, sports, bikinis. 18-year-old guys have a lot on their minds. Accidentally breaking the law probably isn't one of them. Yet that's exactly what young men will be doing if they fail to register with Selective Service. So if you know a guy turning 18, do him a favor. Remind him. Fortunately, it'll only take him a few minutes because that's all it takes to register at SSS.gov. Then he can get back to his distractions. I mean homework. SSS.gov. Register. It's the law.
